The group will make a recommendation to the Competition Committee on how to improve the most perplexing rule in sports.

NFL Commissioner Roger Goodell said Friday morning on SiriusXM NFL Radio that understanding the nuances from every perspective is vital when making any adjustment.

"I think what we have to do is we have to settle on the rule that is properly communicated, properly understood and be officiated in play that, from a players' perspective, they feel comfortable with," Goodell said. "So we're gathering input on that. We've got a sub-committee that's working and analyzing all the data, trying to come up with suggestions for the Competition Committee to consider. We have some former players, former GMs, former coaches, former officials, they're all going to be working on it, and we want that input.

"We want to be able to understand better how we actually define how long they have to keep possession of the ball, and that's really the key issue and sometimes people disagree with the rule, but a lot of the time, the officials have it correct," Goodell continued. "So we have to get that where it's consistently done and it's consistently understood."
